I revisited one of my best sellers from 2013 (Avera) and gave it some extra attention. What was a single weight font has now been transformed into a collection of 12 fonts. This particular collection includes all of the Serif alternatives (6 fonts).

Psst - The download comes with both TTF and OTF font formats. I recommend installing the OTF's first as they are of higher quality. But if you have any issues, try the TTF (sometimes, Microsoft Office and similar programs can throw a wobbly over OTF fonts).
